However we believe that only some processes of pair creation should conduce to the creation of space and time in the universe. Following the Standard Model we suppose that the basic fermions (electron, for leptons, and proton, viewed like quarks u, d, for barions) can determine the processes of space-mass creation in the universe, because they are basic structures for the IQuO's couplings.\\  We observe that in the present universe a feasible candidate for the transformation of energy in mass (involving electrons and nucleons) is the beta decay into the stars. However we don't exclude other creation processes space-mass in the universe. If the birth of a basic massive particle occurs in a local region of the universe, the resulting increase of universe's \emph{volume}, dued by a IQuO's chain, could be expressed like a global transformation of spacetime.\\  This is consistent with quantum mechanics: a particle whit defined wavelength is associated to a line of oscillators with \emph{extension} equal to that of the universe (see the collapse process of the wave function).\\  In this way the galaxies (stars), besides being the source of a gravitational field, could be the source of a \emph{field with an increasing space} or an \emph{expansive field}. field}.\\   It's obvious now that the cosmology built by us is based on an increasing universe in space and mass, in which the proton-neutron transformation plays a key role.
